Not sure but if you ask in the Titanic (opposite Rila swimming pool), they have internet access and should be able to tell you more. Depends if you are taking your own.
Check menu prices before ordering. Pay as you go along - less chance of being ripped off for drinks you haven't had. Avoid the Buzz Bar - unsavoury reputation. If you get the chance or want a change - try getting a taxi to Samokov Town 15-20 lv max - negotiate fare before getting into taxi - and try a restaurant there. I can recommend the Old House, Central or Kokoshkovo Kushta. It is best to prebook, especially The Old House. Ski instructors will have the numbers ...
Word of warning.

Prices are so much cheaper and food is fab.
Hope that gives you enough info to eat and drink well all week.
