Went to the Lower East Liquor Bar and Bistro in Canary Wharf using their 50% discount lunch offer on Friday.
The steak burger and lobster BLT were both competent affairs with excellent fries on the side (served in mini deep fat fryer baskets - brilliant!). The high light of the meal was an excellent banana milkshake.
Overall a reasonable experience but nothing to write home about. Certainly value for money with the 50% discount, not sure I'd go back if I had to pay full price.
