I am fairly new to sushi (but love what I've had) and want to try more. The problem is that I don't have the money to go to a place like Jewel Bako get an omakase. Can someone recommend a place that is on the inexpensive side and where I can sit at the bar by myself, have some good fish, and learn from the chef? Prefer recs below 30th St. Can anyone comment on Cube 63? I see they have omakase starting at $30. What are the prices like at JB Makimono? Do they have a suchi bar to sit at?
