We spent a week or two up there last summer, staying in a caravan park. Fabulous scenery, and great beaches. I thought the water was actually warmer than I expected, probably because the beaches were well inland (in the respective bays), but crystal clear water! Get a wetsuit (one of the cheap "shorties" from Lidl and it won't bother you at all. Jump in off the pier wall. Pubs and restaurants not plentiful, and nothing special either. Beautiful place though.
