"I'm an avid user of toptable, like previous person, but there are reasons for using both. Toptable is good and free, but if you dine out a lot then you'll find they only normally have 20-30 decent offers, and they're the same restaurants all the time. Also, I went to Mango Tree and was told I'd have to vacate my table by 7, so that was a waste of time. tastelondon has 500 restaurants on, and the offers are all 50% or 2-4-1, and as far as Ive experienced they only exclude Fri and Sat nights. I'd say buy a card (through Time Out, then you get a free guide) but only if you go out fairly regularly (maybe once a month)."
