The Hatters have belied their lowly budget all season and are now just three games away from realising their top-flight dreams.
Nathan Jones' side host Huddersfield Town at Kenilworth Road for the first leg of their Championship play-off semi-final.
If all goes well, the next time Luton fans return to the 10,356 capacity stadium, they could be in the Premier League.
talkSPORT's own and Luton fan Faye Carruthers said: "The noise that it generates is absolutely incredible.
"And I would say a very hostile environment for people to come to, however, it's charming at the same time."
Kenilworth Road is one of the most unique grounds in the country as well as being one of the oldest - having first opened in 1905.
Premier League fans accustomed to attending Tottenham's £1billion stadium could be in for a rude awakening on a Luton away day.
But Faye added: "People will mock us for our ground and that really annoys me actually.
"I would much rather go to a ground like Kenilworth Road than go to a brand spanking new stadium with no soul!"
The entrance to the club's Oak Stand is highly unusual with travelling supporters forced down a small alleyway at the side of the stadium.
Fans will then have to walk up a flight of stairs into the away stand, which is packed tightly in between neighbouring residential houses.
Luton's official website claims supporters are 'guaranteed an exciting and unique matchday experience' regardless of the result.
talkSPORT's Faye said: "People saying it's not fit for the Premier League have never been there - they'll make it fit for the Premier League.
"The club will invest what they need to in order to get it up to the Premier League standard if they need to.
"And it will be a ground that everybody wants to tick off their list."
The Bedfordshire outfit have already welcomed one Premier League side to their iconic venue this season having faced Chelsea.
The Blues all-star team struggled to get to grips with Kenilworth Road having twice fallen behind before scraping a 3-2 win in their FA Cup fourth round tie.
Faye revealed: "I took my whole family to that game and the atmosphere was absolutely incredible - we made it very difficult for Chelsea and we ran them very close."
It has been a sensational journey for Luton, who were relying on a hat-trick from former Watford striker Andre Gray to beat Hyde United only eight seasons ago.
Luton's current squad was assembled for just £1.5million, which Cristiano Ronaldo rakes in just over every three weeks at United.
Despite that, the club's hierarchy confirmed plans in place to move to a plush new 23,000 stadium should they reach the top flight.
Luton CEO Gary Sweet wrote in his programme notes last month: "We are currently surveying our facilities for Premier League compliance and to even prepare to make our old girl fit for purpose for the top table is not an insignificant task, especially for the demanding broadcast and media requirements.
"Significant work will have to be planned for, ready to pull the trigger (should we be the lucky ones), to then be completed in record-time during the close season.
"Quite simply if ignored now, Kenilworth Road would be incompliant and substandard, not just 'quaint.'
"We simply will not allow for Luton Town or Luton to be seen as sub-standard, and if we can achieve a satisfactory level of compliance in the eyes of the Premier League with minimal dispensations, there is no reason why our charming environment shouldn't be embraced by those other member clubs as an enhancement and broadening of the rich tapestry of venues to visit."
talkSPORT will have exclusive coverage of Luton's Championship playoff semi-final first leg at Kenilworth Road on Friday, May 13.
