With a full house of 442 guests, made up of the firms and the award sponsors only, we will be celebrating the best of Welsh business in an atmosphere that is very different to your standard business dinner.
Last year's winning company, Unit Construction and Engineers, has already announced a major project in the last few months and it was great to see that another previous FG50 company, Moneypenny, has recently stated that it will be creating an additional 100 jobs in Wrexham.
So which company will win this evening?
Well, I am afraid the result is not officially announced until the 52 page Western Mail supplement on Wednesday but I can reveal is that all fifty companies have made an incredible contribution to the Welsh economy both in terms of employment and increased sales during the worst recession since the 1920s.
More relevantly (and WAG policymakers take note) this growth has, yet again, occurred across a range of industrial sectors.
This year, I have also asked the opinions of the entrepreneurs as to what they would do if they were economic development minister.
As you can imagine, some interesting responses and I will publish these next week.
