An Asunción institution, Bolsi is Paraguay’s answer to the beloved American 24-hour diner. This classic cafe serves up door-stopping tuna and palm heart sandwiches alongside slabs of rib-eye steak and Lebanese-inspired beirutes (stuffed pitta bread). Paraguay’s river fish surubí is plated with flair – try it stuffed with sautéed shrimp in a creamy coconut sauce. Bolsi claims to make the best caipirinha in the city and has some tasty local reds on the short wine list. The place is often packed with families on the weekends, so head over for an early lunch or dinner to secure a coveted table.
