Blind Tiger on Cowgate opened on May 17 in the old Tamu premises and has become well-known for wide range of craft beers, cocktails and coffees.
But while the upstairs floor is light and bright, now the lower floor has opened to customers - a quieter, more chilled affair with a style blending the voodoo occult with New Orleans and gothic imagery.
Skulls, candlesticks, a 'tequila rifle' and low light create a mysterious, unique atmosphere for convivial conversation while you sip a rum or tequila with table snacks.
There's even a seat which would once have been used as a cot in India, ideal for a chat with the friendly skeleton nearby.
Owner Neil Treliving hopes that the new attraction for Peterborough, with fewer than 30 seats, will give drinkers a new option for autumn, and of course Halloween.
He said: "We wanted something a bit quieter with lower light - we can play vinyl down here, and it's just a completely different feel for people to enjoy.
"It's all about the beer upstairs, but we thought we'd bring the spirits and wine - which we sell a lot of upstairs - down here.
"It's a mix of styles, of Day of the Dead, voodoo, Mexican, macabre and Gothic. There's nothing else like it in Peterborough really and it's just a case of telling people about us.
"A lot of people in Peterborough aren't coming out, and are still fearful about what's going on, so perhaps a smaller, spaced out venue would be better for them."
The lower floor will be table service with bookings only, and it's ideal for hen/stag parties, cheese and wine tasting, games and perhaps acoustic nights in the future.
And the venue is supporting local business, with a partnership with Amps Wine Merchants in place.
