We tried this on Sat pm, we turned up at 8 & got 2 seats at the bar, no one offered us a table even though there were some free so I'm interested that you can book them?
The food was great, we tried some sherries & the service was fine, my only comment would be that the bar stools weren't v.comfortable as they kept spinning around & I had to jam my knees against the bar to keep myself from sliding onto the floor.
I would go back but ask for a table next time
