Extremely crowded, but still fun. There's a separate bar area where you can get drinks and food, which aren't allowed in the putt putt area itself. Worthwhile to stand in line with a drink until you're up to putt.
Vietnamese sandwiches here are amazing. Extra pickles for a small charge and they add in a little jalapeños to give them a little kick. $6! Park at the Japan Annex Garage or there's some street parking around the corner off Geary.
Come here for brunch on the weekends. Expect to wait 30 min to 1 hour, but it is totally worth it! There's also seating in the garden outside behind the restaurant. Ask for a spot out there if the weather is nice.
