I ordered ahead online for the Shattuck location for the pizza of the day, which was corn, pineapple, chile pasilla, mozzarella, french feta cheese, cilantro-lemon zest, and garlic olive oil. You can order online for pickup either on their website or on DoorDash, either way the prices are the same (in fact it appears they're using the DoorDash client for Sliver's own online ordering). The only catch is that you can only order ahead a whole pizza and you cannot order a half pizza, a slice, or a sliver. I'm still glad I did because I was able to skip the long line at noon from the lunch rush. I only saw two people working the front but they were doing a good job with handling the long line. The workers included a complimentary bag with small amounts of sauces.
The pizza itself was delicious, I personally do like pineapple on pizza, and it was warm and had plenty of thick, flavorful cheese, so great for any dairy lovers. I didn't find the cilantro-lemon zest to be overpowering (but I'm also not someone who finds the taste of cilantro intensely negative). Though they apparently used chile pasilla, it was not enough for me to find the pizza spicy at all. They also included slivers which is great since when I've gone to a few other Sliver locations like the Oakland Uptown and Montclair, they unfortunately did not throw in any slivers when you order a whole pizza, but this might just be a reflection that these non-Berkeley locations receive lower traffic and actually bake the pizzas to order instead of having to mass prepare a bunch to handle the lunch or dinner rush.
The Shattuck location does have a couple of outdoor tables. There are also some other free tables in the downtown Berkeley BART plaza, but the chairs tend to be popular around noon.
