I understand why this BP gets such low ratings. We didn't have the best experience either. Upon arriving, the place only had a handful of tables occupied, but it still took a while to be seated and even longer for the server to show up.
After that, it didn't get better. First, even though the menu says "all sandwiches and tacos come with fries", no fries came with my order shrimp tacos (when I asked, I was told I could pay extra for them). Beverages were really watered down too and we sent one back. And to top it off, the price of the watermelon sangria on the bill was higher than on the menu.
Not big issues, but it doesn't seem details are the strong points there.
Better service, food and value easily found elsewhere.
