LTC is just up the street from Rainbow. Capt Frenchy's is just down the street from Rainbow. Both offer chairs with pads. I have been told chairs are free at LTC if you eat there. Frenchys had a shower that you can use if you want to shower and change for dinner. Can't help on the parking at either place, though there is paid parking, 5 Euro, a block or so north of LTC, it is on the Left hand side of the street as you are driving towards LTC and Rainbow.
