In reply to Steve_90:
Bishop is brilliant. I only spent four days there but can't wait to go back. The scenery, the rock(s), the weather... Here's some random beta:
-We camped at Brown's Millpond campground. It's basically an RV park but it was very quiet in mid-May (1 tent in addition to us + a handful of RVs). They have (pay) showers. It's midway between the Buttermilks and the Tablelands and close to Bishop so it's handy. It's not really scenic but it's quiet. Can't remember the price, maybe 25$/night? There's cheaper options for sure: The Pit is 2$ I think but has no water. There's a water spigot outside the White Mountain Ranger District Station in Bishop town. There's also the Pleasant Valley pit a bit further down the same road, it's 14$/night and supposedly you get water but from what I read the spigots often don't work, plus you have to pay at some cash machine. The Horton Creek campground also has water, though it's a bit further from the bouldering areas.
-Foodwise, if you like burgers, I strongly suggest you stop by the Burger Barn. My friends and I loved both the veggie and non-veggie options. For breakfast, the Great Basin Bakery and Cafe is excellent, and this is coming from a Frenchman who grew up two doors down a bakery. The Mountain Rambler Brewery has a friendly and lively atmosphere and good food. The Mexican restaurant is OK.
-The Bishop Bouldering Select has about 600 problems which should be enough to entertain you for a while. It features the main areas: Happies, Sads, Buttermilks, Druid Stones and Rock Creek (the latter is supposed to be similar to Yosemite and is further down the road toward Mammoth Lakes, also higher so cooler).
-Eastside Sports and Mammoth Mountaineering rent pads. Prices are the same I believe, 10$/day.
-If you're unlucky and weather is crap, go check out Mono Lake after Mammoth Lakes (~1hr drive, maybe less?). Cool tufas, bubbling water in places, birds, great scenery (reminded me a bit of Iceland).
Have fun!
