A lively, castle-side pub with crowd-pleasing carvery, fish and chips, and strong atmosphere, but service and cleanliness can be inconsistent and some visits show real operational rough edges.
Palace Vaults delivers reliable pub comfort food in a distinctive historic setting that draws steady crowds, but inconsistent execution and variable service attentiveness prevent a higher grade. Strong food quality and excellent location appeal are offset by uneven consistency across visits and gaps in service reliability, resulting in solid neighborhood dining rather than destination-worthy performance.
Palace Vaults feels like the sort of Caernarfon pub that wins people over with location first and atmosphere second: castle views, karaoke nights, live music, dog-friendly vibes, and a room that can feel warm and buzzing on a good night. One reviewer summed up the mood as instantly welcoming, while others kept coming back for the lively, slightly old-school pub energy. On the plate, this is reassuring pub comfort rather than culinary theatre. The menu is built around carvery, burgers, fish and chips, wraps, and platters, with enough vegetarian sides and a few meat-free mains to keep most groups moving. The food gets strongest praise when it stays simple and hearty: generous roast plates, solid chips, and value that feels fair for a central tourist location. If you want inventive cooking, look elsewhere; if you want a dependable pint-and-plate stop with a castle backdrop, this is much more the brief. For kids, the menu is workable rather than magical: fries, chips, burgers, fish finger sandwich, halloumi wrap, and carvery-style plates are all familiar enough for most children. That said, this is still a pub with lively evenings, so families will likely be happiest at lunch or earlier in the day rather than during karaoke or live-music hours.
