Playing on the innuendo of a meat market as a singles' bar, the playful atmosphere at the Meat Market in Covent Garden won me over the first time I went there. It's in a loft overlooking the Jubilee (flea) Market, and the rafters are hung with irreverent fake personal ads and suggestive signage. It's a much more laid-back experience than its sister restaurant to the North and West, Meat Liquor (see my 2nd update for details). I usuallly get the Dead Hippie, but this last time I had a Black Palace burger, which trades the dead hippie sauce and minced onion for grilled onions. Excellent, excellent, excellent burger all around. It's a little bit messy, but worth the indulgence. Order the beige milkshake (bourbon + maple syrup) and take some friends to split the chilli cheese fries. They're a little unusual, but very tasty. Also, this is the first place I've found in London with decent jalapeno poppers.
