Hi Ladies, I am travelling to London with my 10 month old in a day...I am planning to stay in Piccadilly Circus...Just have a few questions...It would be great if someone could help me out on these! 1) Is car seat mandatory in London?( I will be taking a cab from Heathrow to the hotel in Piccadilly) 2) If so, can the cab guys get a seat, if we request it? 3) Cheap and good places to eat in and around Piccadilly 4) Is there any Tesco or similar store around P? Thanks in Advance, Lakshmi
