Our hotel room was just across the street from mama's but every morning I opened the window and find a huge long line and became very discouraged.  Finally this morning it didn't seem like there was a line so we were really excited about eating there, but of course, it was closed on Mondays.  So I guess we couldn't have everything and so we gladly had dim sum instead, I decided that until next time, I will just think it was not so good :)
