Run by three Italian natives, 2 Spaghi is a small pasta shop in Budapest with an endearingly simple mission: serve fresh, made-to-order pasta dishes quickly and well. You are invited to pair a variety of pasta shapes (fusilli, bucatini, tagliatelle, etc.) with an often-changing list of sauces. On any day, there might be cacio e pepe, carbonara, puttanesca, amatriciana, and aglio, olio e peperoncino sauces listed on the blackboard. The good news is that you can't go wrong with any of them. Also, most options cost €10 or less.
Hand-rolled, stuffed pastas like ravioli are also available (go for the spinach-and-ricotta filling with a mixed-cheese topping). Gnocchi is made on Thursdays. If you have any stomach space left, round out your meal with a light panna cotta topped with strawberry sauce (€2).
Note that 2 Spaghi is inside Gozsdu Udvar, a tourist-heavy courtyard lined with overpriced bars and restaurants. I can't help thinking that this charming pasta joint would deserve a more distinct location, but if you don't like the ambiance, you can also just buy some fresh pasta to go.
