Mustard

Mustard is hands down the best spot in South London for sandwich and salad boxes—perfect for both takeaway and office catering. The customer service is outstanding, with incredibly friendly and helpful staff—special thanks to Sharon for always going above and beyond! We order regularly for office events, and Mustard consistently delivers delicious, fresh food with exceptional reliability. They are also excellent at accommodating dietary requirements, with everything coming clearly labelled. Deliveries are always punctual, and Ricky, one of the drivers, is a pleasure to deal with—always cheerful and professional. I can’t recommend Mustard enough for lunch or catering needs. Thank you to the whole team for your consistently excellent service!

Delicious Toasted Sandwich, warm chickpea curry, fresh salad and so much variety of selection to choose from. We were a bit clueless on how to order but everyone at Mustard was so sweet and friendly and patient with our questions. We loved our lunch there, dad wanted to go back so badly but we left SOUTHWARK already. Cant wait to go back again

Quick service, staff were friendly and the food is amazing. I got the protein box which comes with a choice of protein and 4 different sides. I got the chicken and extra halloumi. This whole meal cost me less than £12 with a drink.

My regular lunch spot when I’m in the office They do great salad boxes (loads of variety in greens, carbs and proteins), jacket potatoes and snacks/drinks. Really friendly and quick service and delicious lunches!

I visited Mustard London recently and it’s safe to say this place knows exactly what it’s doing. It’s one of those neighbourhood spots that feels effortlessly stylish without being try-hard—just good food, good service, and a chilled-out atmosphere that makes you want to settle in. The first thing that stood out was the menu—it’s British comfort food, but done with real care and quality ingredients. I had the Mustard cheeseburger, and it was genuinely one of the better burgers I’ve had in a while. Perfectly cooked patty, soft bun, just the right amount of sauce. Nothing over-complicated—just really well-executed. The truffle mac & cheese on the side was also dangerously good—rich, creamy, and properly indulgent without going overboard. You can tell they’ve thought about balance and flavour, not just loading things up for effect. Drinks-wise, there’s a decent little cocktail list and a good mix of wines and beers. I had a classic negroni, and it was well made—not too heavy on the Campari, which I appreciated. Everything felt fresh and well-presented, but without the pretentiousness that sometimes comes with places that care this much about detail. Service was friendly and laid-back—attentive without hovering. The staff seemed to genuinely enjoy working there, which always adds to the vibe. All in all, Mustard strikes that perfect balance between casual and quality. It’s the kind of place you can pop into midweek for a low-key dinner or bring friends at the weekend for something a bit more special without blowing your budget. I’ll definitely be heading back—next time I’ve got my eye on the Sunday roast

I come here twice a week on my lunch break. The food choice is alright. Never changes though.. quite monotonous! One thing I noticed and think it’s not right is that I never seen the staff disposing of used gloves periodically. They use card machines, handle kitchen tools and pat each others shoulders during service without changing their gloves even once.. not good. Could do better!

One of the friendliest customer experiences I’ve had in a long time. The staff are very pleasant and cheerful, providing top quality food that’s always presented with a smile.

Mustard is the best sandwich and salad box place for takeaway in south London near Borough. The protein salad box with spicy chicken, spicy chick peas, cucumber / tomato / black olive salad and spicy rice with coleslaw and hummus is probably the best takeaway salad I've ever had for only £7.50. And the start are really friendly and helpful.

Cute little sandwich shop!...they have coffee, tea, pastries and loaves of breads as well. I got the Pesto Chicken sando and it's good, but nothing to write home about. That being said, I may have ordered wrong so I'll give this place another shot. Most others in line ordered the Coronation Chicken

Excellent customer service. Polite and helpful staff and caring owner. Very clean and always willing to listen stem and improve.

Cool sandwich shop located between Borough and Elephant & Castle. I normally go for the salads here, of which there is a good variety and i tend to include several hot falafels into the mix as well...tasty :-) Prices fairly standard and reasonable, there are often queues during the lunch period that extend onto the pavement which is always a good sign. Was recommended by a work colleague who's a regular.
