What a disappointment.  Supposed to have dinner at 8pm, party of 12.......after waiting 45 minutes AND some of the party paying for drinks at the bar, we are told there is no room for our party.....somehow the reservation was missing?????  My personal thought....they also had a party of 40...hmmmm which would make them more money?  Turned out for the best for our party....we went to GEISHA HOUSE on N. Decatur and had a WONDERFUL diner, EXCELLENT service, YUMMY food...so I guess Thank you Osaka for losing the reservation....we went somewhere else where our business was appreciated and had a great time!  Oh and won't be back to Osaka!
