Went with some friends on a Saturday. Very long line up at 6pm. Because we needed a table of 4, we waited for about an hour. The place is tiny, and we sat at the corner squished between the door and the fridge. The waitress is very friendly and smiley. I had a shrimp okonomiyaki, which is a "pancake" paste. We also shared a tortilla with grilled meat and tomato; meat is very flavourful.
The pancake is quite large and filling! The texture is softer than fish paste but still has small whole shrimps inside. Comes with some sauce and lettuce. We found the place by ratings, and when you're waiting in line for so long, you know what you're in for.
