The place has got what it takes as a pub. The beers on tap include their own sort of beer which you most probably wont find anywhere in the city. If we understood them correctly, Patrick has its own recipe of beer but makes it in one of local breweries.
Not many of the tables are especially appealing. Guests of Kharkov might have noticed that its not that popular to sit at the bar in most bars. Patrick is different - you feel even more comfortable at the bar than at the table.
Their biggest disadvantage is ..the smell. Since the place is located almost underground, all the aroma from the kitchen comes to the main room. If you don't mind wearing kitchen flavour on your clothes, then it should be a problem :)
