Cons: Used to be a new "kid on the block" a couple of years ago but, being a new thing, quickly got overcrowded, services became less than friendly "we have no tables now…"
Pros: Now the hype is over, and the places (a few in Kyiv) are mainly know by their co-located bread shops (boulangeries) supplying tasty but expensive pastries from their own bakery somewhere next to Kyiv. Early XX century "bourgeois"-style Parisian interiors, prime locations: one some 200 m away from the Independence Square – the capital city's centrepiece, another in the 5 star hotel, 100 m away from the city's main thoroughfare (a spacious, with a "kids' corner": a small slide, toys, etc.). Now, there are 4 or 5 bread shops throughout the town. Sandwiches are tasty and large, a bit pricey (starting from 6-7 USD up).
Useful tip: call in and book a table for that Independence Square location if you're going to pop in on a Friday or weekend evening.
