The new owners of the Horse and Groom on Carholme Road said the pub will finally reopen in November, after being closed for almost two years.
Ever So Sensible group is spending £250,000 more on the pub to have it completed in time for an opening next month.
The public house would focus on good food, wine and ales, with many choices locally brewed.
The extension to the side of the Horse and Groom is already nearly complete, which will add extra room for diners.
The outside will also receive a facelift, with decking and the garden area landscaped.
Managing director Chris Bulaitis (pictured) said: “The Horse & Groom is one of many wonderful old pubs across the country that’s been closed for far too long.
“The building has a real sense of history and we’re aiming to bring back some of that original character to create what I would describe as a ‘real pub’.
“We’re planning to have five guest cask ales, some of which will be from small local breweries, as well as an exceptional wine list.
“Our food offering will be freshly cooked, using local ingredients, and you can expect to see classic dishes such as slow roasted belly pork, a fantastic selection of steaks, a range of gourmet burgers and, of course, Lincolnshire sausage, but with our own twist of red wine and onion marmalade gravy.
“This is all about creating a venue that isn’t part of a chain, that offers a friendly, relaxed atmosphere for people to come and enjoy classic food and a wide selection of drinks.”
Ever So Sensible obtained the leasehold for the Horse and Groom for an undisclosed sum earlier in the year.
The group also own Dogma on the High Street, and a number other bars in the East Midlands.
