I went to the Tickets website:
http://www.ticketsbar.es/web/en/#home and they didn't have availability for our dates.
Reading their booking instructions, they open seating, 60 days in advance. The only way to reserve is through their website. I tried on January 20th and they had availability for March 19th, 20th & 21st. We needed March 11th

but didn't know about this place until right now.
What time do they open, some of the posts state arrive early if you don't have a reservation. What time is that?
Any other great suggestions for one memorable meal / tapas in Barcelona? Would like to try food native to the area, high quality, doesn't have to be a fancy place. Food quality #1, Atmosphere (more locals, less tourists) #2, Decor #3.
