Feeling like eating Spanish food (Paella or zarzuela), Meson is the place to go. I've been there twice for diner. The menu is straight forward. You do not have many options. This allows the restaurant to focus on few dishes that end up very good.
I ordered the Paella. It is well-stocked with chicken, shrimp, clams, mussels, chorizo, tomatoes and green peas.
I also tasted the Zarzuela. The cod, shrimp, mussels and potato bouillabaisse where marinated in a delicious spicy sauce.
The restaurant is cosy. They have a nice bar. I posted a pic of it. What I also like is the industrial design luminaire.
We also need to mention that the service is impeccable. They were able to handle a table of eight people on a Friday night with no delays in serving the food. Lets not forget the waiters that are very professional and helpful.
Overall Meson is a good place to dine on a weekend with friends or if you're on a date.
I only have one comment to make. Even though they have a big wine cellar, they also need to focus on beer. They only serve 1/2 Pint glasses. They need to go for the pint.
