Pompi is the go-to spot for tiramisù in Rome, a casual, counter-service bakery known for its creamy classic that you should taste first and for seasonal or pistachio variations if you want something different. Expect a short queue at peak times, quick service, and options to eat at a few small tables or take your dessert away; portions are rich so one serving can be shared. Prices are reasonable, cards are commonly accepted but bring a little cash just in case, and timing your visit before lunchtime or after the evening rush will help you avoid the longest lines.
