Firestone Grill

Food was delicious and hot when ready. The fries are definitely a 2/5, soft, and not that great, but the onion rings are incredible! All of their burgers and salads are really good as well. The napkins are as thin as one-ply toilet paper, so just expect that everyone will need to wash their hands afterwards (or bring wipes!)

Super popular, big portions, reasonable prices. Really long lines, but they moved quickly. Staff was super efficient. Worried that we wouldn’t get a table, but due to there being so many available, turnover was quick and we found one easily. Food was ok, portions large.

Average burger joint but make it Costco sized! I got the cheeseburger, basket of fries and some onion rings and was satisfied but not overly impressed. The basket of fries is MASSIVE! The fries come seasoned and pair well with a side of ranch dipping sauce. The cheeseburger was pretty average, as was most of the food. The plus to this place is that it has tons of seating, indoor and outdoor, and serves large portion sizes while being located in downtown SLO — making it easy to watch the game. Service is quick and friendly!

A lot of great food! We went on a Tuesday night and the line was out the door so you know it’s good. There’s a lot of indoor and outdoor covered seating. Quick turnaround from order to food being ready despite the number of customers. The pictures are after we’d gone through half the food…

Good enough food for cheap prices. I got the grilled chicken sandwich and while it was nothing to write home about, for $9 I was happy with what I got. The French fries could have been crispier, but were seasoned really well. The onion rings were amazing, perfectly crispy and well seasoned. And good luck in the bathroom gentlemen, the urnals have no dividers.

Decent BBQ. What could go wrong with juicy pork ribz rack with BBQ sauce? You got it! A bucket of fries are missing. The half rack combo is a pretty good deal. But I still recommend you go full rack if you a meat lover. Tri-tip taco is also pretty good and healthy as they put a lot of veggies in it. And trust me, it’s pretty huge taco. I would definitely come by every time I visit this town or road trip to South Cal.

Spacious indoor and outdoor seating, fast service despite very long line, reasonable price, different seating options (hard to find vacant ones though) Cons: Food was just ok. More fast food quality than a diner quality.

It's the best tri tip ever. It is a great sandwich and burger place. They have salads, too.
