About a block or two to the West on the southside of Belmont there is an indoor one level parking garage. It's small as it holds maybe 20 to 30 cars. Rates range from $4 to $40. If you can get out of the theater within 2 hours it'll be only $6 to park.
Street parking
There is also valet on most nights.
There are usually open spots for street parking.
