I am a Trad who assists at the SSPX.  I was invited to a wedding on a Friday night.  Since I observe the Friday Fast at all times of the year but would like to enjoy whatever the main course is at the reception.  So, should I seek dispensation from my SSPX priest?  Or should I just follow the novus ordo standards and pray a complete Rosay or such penance as that?  Or should I stick to the meatless items?

If it were me, I'd stick to the meatless items.
I considered this scenario recently when invited to a Friday wedding, but didn't end up attending at all due to distance and time of day.

Getting married on a Friday sounds very practical for a number of reasons, including cost and ferial day.

That being said, I'd go. Every wedding I've been to had meatless options. And most will, anyway.

If a deacon is presiding (no need for inverted commas), there can't be a NO Mass and that's probably better.

Why would you consider asking for a dispensation if you are a Catholic? Can you not go without meat? Why not give a quiet witness?

Go Meatless or wrap it up and save it for lunch next day.

If Marriage is a sacrament, why is a deacon presiding?
Where is the priest? At gαy bar?  

Yes, you should pray the Rosary during the Mass.

Deacons are part of Holy Orders in the NO, so they can confect the rite of marriage

Learn something about Church teaching before you spout your mouth off.  The couple confers the Sacrament on each other; the priest/deacon merely witnesses the event for the Church, and then imparts a blessing.

Abstaining from meat on Fridays is meant to be penitential. Lucky you! For you have the opportunity to make it even more penitential than the average catholic by declining a delicious main course at a wedding reception! Take the high road- you'll get more enjoyment out of not eating it in the long run. :)

When I see a quote like that of the OP "would like to enjoy..." it really clunks in my ears.

At least the OP is honest, but he is honestly broadcasting to the world that he has an inordinate attachment to food.

We shouldn't "seek to enjoy" such base pleasures of the flesh. If your taste buds work, you will certainly experience plenty of pleasure in this life. Especially if you live in the USA, where food is cheap and plentiful, even among the poor. We shouldn't cater to our concupiscence -- we should fight it.

If God sends us some consolations and simple pleasures in this life, then fine. But we shouldn't seek to "enjoy ourselves" and "enjoy life" as much as possible, even at the expense of A) passing up opportunities for penance, or skipping penance altogether and B) even committing venial or mortal sin.

How do you know if you're enjoying food a bit too much, or that you need to practice more mortification in your life?

Well, for starters, if you ever find yourself chafing at something as easy and basic as Friday abstinence from meat...
