Monkey Mash sits on Praça da Alegria at number 66B, a few doors from the square's better-known speakeasy, and it is the playful half of the equation. The team behind Red Frog built it as the daylight-bright opposite of their dark award-winner: tropical, fast, and centered on sugarcane and agave spirits.
Who would love it: drinkers who want serious technique without a hushed room, and anyone working through rum and mezcal rather than gin. Who would hate it: purists who think a great cocktail requires dim lights and a dress code.
Praça da Alegria itself sets the scene, a leafy pocket square off Avenida da Liberdade with Avenida metro three minutes away. The square has quietly become Lisbon's densest cocktail corner, with Red Frog's unmarked door a few steps along, which makes a two-stop comparison crawl the obvious play. Start bright at Monkey Mash, finish dark next door, and argue about which philosophy wins on the walk to Bairro Alto.
The room
Expect color where most Lisbon cocktail rooms go shadowy. Portugal Confidential describes the space as a clean, contemporary take on tiki, with greenery, murals, and a long bar built for watching the blender-free production line. It earns a spot on the World's 50 Best Discovery list, the same scouting index that tracks its sibling bar.
What to order
The menu runs on cachaça, rum, tequila, and mezcal, with most cocktails around 12 euros, a fair tariff for technique at this level in this part of town. Time Out Lisbon points drinkers toward the house tropical builds rather than the classics, and the kitchen-style prep behind the bar means clarified juices and house ferments show up across the list. Ask for whatever the bar is running as its seasonal sugarcane special.
Who it is for
A second stop after Red Frog when you want the volume turned up. A date that needs conversation and color in equal measure. A group that cannot agree between rum and agave, since the list splits the difference.
Best time to go
Doors open at 6pm Monday through Friday and 7pm Saturday. The room runs easiest before 9pm; after that the Friday and Saturday crowd holds it at capacity until close at 3am. Sunday it stays dark, so plan the tropical leg of a Lisbon bar crawl for any other night.
The crowd
Before 9pm the room runs international: hotel guests off the Avenida da Liberdade, cocktail tourists working the 50 Best Discovery list, and dates that started at the miradouro up the hill. Later the balance shifts toward Lisbon's own bar industry, who treat it as the bright room to decompress in after their shifts.
The bar seats reward solo drinkers who want to watch the prep work. Tables suit groups of four; larger parties should expect to stand on weekends.
What regulars say
Yelp and Tripadvisor reviewers converge on the same praise: the drinks taste as considered as Red Frog's at a friendlier volume, and the staff steer indecisive orders well. Portugal Confidential's review singles out the playful presentation as the draw, with serves arriving in ceramics and tiki vessels rather than coupes.
The recurring practical note is the Sunday closure, which catches out visitors planning a weekend crawl. Book nothing, arrive early, and let the bar's pace set the night.
