Wrong way Joe.
If you want fish and chips, head toward Pajo's.
If you want to catch fish, head the other way into the park. There are three bays with sandy beach at Garry Point Park. Although fishing on the beach is ok, for coarse fish in general, most of the fishing is done on the rocks on each side of the bay. When the pink salmon are coming through during the incoming tide, spincast from the rocks. My recommendation is to fish the rocks facing the first bay (the bay in front of Pajo's) once you get into the park. You would be facing the entrance of the marina. Quite often, if pink salmon are coming through, they would enter that bay, circle around, before swim out to the main channel once again or swim through that narrow channel.
If no salmon are around, spincasting from the rocks with small spinners will entice some rather big northern pikeminnow as well.
You can also bottom fish with bait (shrimp, worm, etc) by casting out really far. Don't drop your line just in front of the rocks, otherwise you would snag up. With bait on the bottom, you are likely to catch the odd dogfish, pacific tomcod, sculpin/bullhead, flounder.
