In the uk a pint is £3+ so 4-5 lev is great value even better when you have skied all day. I go to borovets to ski and chill out as i work hard all week and don't get a chance to spend the week skiing and drinking.
I know from going to Bonita's in samokov its even better, 18 of us went 2 years ago and have a great time, can you recommend some more places?
