"Half-price on selected cocktails, beer, wine, and mocktails from 4pm to 7pm every day If you’re into Happy Hours that come with a side of tranquil fish watching, then The Exhibit should be on your radar. This huge three-storey spot in Balham not only has an aquarium that will ignite all those childhood memories of begging for an angelfish at Pets At Home, they also have a three-hour Happy Hour every single day. Grab a velvet bar stool and get involved in tarted-up mango margaritas and lychee martinis." - heidi lauth beasley, sinead cranna
