Those of you who have been around Budapest for a while and read Pestiside (perhaps speak enough Hungarian to understand the pun), selected restaurants throughout Hungary offer their services on Maundy Thursday at a 50% discount.
Restaurants sign up in order to participate and the special is applicable on food and drinks from the regular menu (not a pared down version).
In the past this had given the average citizen a chance to try those restaurants that they may not be able to get to if they had to pay regular prices. The increase in reservations apparently made it worth the while of the restaurants because the event is being held each year with increasing participation.
Unfortunately, the website does not have an English version so you will have to be resourceful (or ask a friend to help). Beginning February 1st the list of restaurants will be listed on the official site and reservations may be made from there also. Naturally, you may also make reservations directly with the restaurant.
Mark your calendars, stay tuned and finally - Bon Appetit!
