18th Feb is the next "Torkos Csutortok" ("Glutton Thursday" :-) ) when more than a thousand restaurants in Hungary charge only half price for all food and drinks.
This means two things to visitors:
1. You won't be able to eat in the most famous and well known restaurants without early booking and it will also be difficult to find ANY place that is not fully booked.
2. If you want to try one of the best restaurants you should book well in advance (practically right now)
www.torkoscsutortok.hu - it's only in Hungarian but you can use the map or search for a restaurant using the "varos" = town and "etterem" = restaurant search forms on the right of the main page.
(I have used this opportunity every year since it was introduced and it really is half price)
