Currently in the Preslav lounge now (downstairs). Can report that there is plenty of space, comfortable seating and it is quiet.
In terms of food, an adequate selection of snack food, some warm bread included, including crisps, cheese topped bread, pates, sweet pepper sauce and some other small nibbles.
Drinks selection decent with a variety of wine, including a Bulgarian sparkling that is similar to a solid glass of prosecco. Bar looks reasonably well stocked with highstreet brands.
WiFi seems to work, but not massively fast.
