Advice for people who wanna attend the Undertale cafe event in Anaeheim, CA
Go early if you wanna get in early - I reached at around 1230pm on Saturday (the cafe only opens at 1pm) and the line was already AROUND THE BLOCK so if u dont wanna wait be the first in line by going early.
Make sure to bring sunscreen and an umbrella - chances are you're gonna be waiting a while in the Sun outside. Like I said I arrived at 1230pm, didn't get to the front of the line until 430pm. So make sure to bring lots of water, food (trust me bring snacks) and something to hide from the shade cos you'll be waiting a while.
Dont expect yourself to be filled after eating - like I said in point 2, bring your own food to eat while waiting. The special event food is really small and you're only allowed to pick one food item from the options (you can get as many drinks as you want though). You also have to leave the cafe in under 20 mins cos of the queue. I would avoid sugary food cos the food and drinks in the cafe are super sweet so too much and you're gonna feel sick.
You're not gonna get what you want on the menu - unlike what they advertised for the event, you aren't gonna get to pick from a list of items on the menu. Most likely you only get to choose between 2 items, which they limited to only 1 person 1 item. When I was there it was the cinnamon butterscotch pie and the spider donuts. You can get as many drinks as you want though. So make sure you actually like the items on the menu if you're gonna commit to waiting 4 hours in line or you'll be disappointed.
Merch is sold out, unless you're willing to pay shipping fees - in person merch at the cafe store was completely sold out when I was there. Fortunately you can order it at the store for them to ship to your house so you can still get merch just not immediately. Unfortunately shipping fees can go up to over $15 so if you're buying stuff make sure not to end up breaking your bank.
Check the places to park - unless you're parking in a garage, most places around the block are limited to 2 hour parking, so if you're gonna be waiting 4 hours you should probably park in a garage or anywhere you can park for extended periods of time. There is a garage nearby where the max parking price is $12 (3 hours is already full price), so keep that in mind.
Sans and Papyrus are in the merch store - when you go into the cafe you'll see cut out figures of the characters. Toriel and Undyne were the easier to spot but if you're looking for the skelebros they are tucked away at the back of the merch store in a photo booth section. Not many people know they're there cos the photo booth is in kind of a inconspicuous spot but just fyi to people looking for them.
Go with a friend - standing in line by yourself in the sun for 4 hours for overpriced mini donuts/pie might sound like a dumb idea to anyone but going with someone makes it at least enjoyable. Bring a sketchbook, even some cards to play while you wait. Some people even brought chalk and you'll find remnants of Undertale, Deltarune and even Homestuck doodles all over the sidewalk. Was it worth the wait? I wouldn't say it was, but I definitely would have regretted it more if decided to not go. And if you are going alone, talk to the people there, everyone lining up there has something that you like too so make some friends while you're roasting in the sun together.
Hope this helps anyone who is thinking of going to the Undertale cafe. Remember to be safe, hydrate, and have fun. The Undertale event is run by the Requiem Cafe from September 15th to October 10th 2022.
