No !
Bulgarian Salads are great
They also do the best Jacket potatoes with various fillings
Chips and cheese seems to be popular with the younger ones.
deep fried spicey carrot and cucumber sticks are nice along with the veggie stews. last year there seemed to be loads of fruit puddings things on go as well...deep fried with some sort of custard or was it cream?? very tasty either way. outside the hotels youll get all the usual pizza and chips stuff as well, so yeah dont worry
