Pros
You get free lunch, but it's only valid within 1 mi. of the office.
Cons
"Scrappy entrepreneurs" is a slogan at Grubhub; Google defines "scrappy" as "consisting of disorganized, untidy, or incomplete parts", which is 100% accurate. Working in Grubhub's marketing department means working with disorganized and incomplete parts, every day. You will be asked to do things at the last minute, your coworkers will gossip about you if you insist on work-life balance, and you may be made to work a weekend if you were sick during the week (as a salaried employee). Don't take the company stock RSUs as compensation, because you will leave with half of what you started with. There is very little room for personal/professional growth, and no resources at the company to help you.
