Prague and I generally eat in local food in bistros hotels, sometimes Vietnamese Vegan Italian or Meaty brewery fare good local restos in Praha , I avoid the old town and Malastrana dues to the hordes of drunks at night and stickybeekers after 9am
Have you dined out in Rye, Lyme Regis or, Geneva,Switzerland or Denmark lately, last year the only place I ate similar -3 to 4 star restaurant meals for less was Soria in Spain and Porthmadog in Wales, Copenhagen prices help the diet IMHO.
PM if you want some suggestions for great waiter service under $10, beer/wine is almost free and tip top
