One word; no hyphen.

shoo-in

Note the hyphen and the spelling. Shoo, not shoe.

Etymology: Shoo-in on etymonline.com

South Beach Wine and Food Festival

It’s South Beach Wine and Food Festival.

Note the order. Wine comes first. Yes, we’re used to food and wine, thanks to the magazine of that name.

Also: Let’s just dispose of the ampersand in there. Just make it an and.

that

In many instances you can remove that from a sentence without changing the meaning Ex.: He said that he wanted to go to Di Fara. She said that it was OK to eat the potato salad.

thought to myself

Thought to myself is redundant; in most cases thought will do.

un-

Most words beginning with the prefix un are closed up: unaffordable, uninspired, unapproved.
However: un-American, un-English, un-European. When used with a proper noun, they form hyphenated compounds. http://www.merriam-webster.com/dictionary/un-

very

One of the first things you learn in Reporting 101 is that nine times out of ten, you can take the ax to very without changing your sentence one bit. It’s a so-called intensifier that gets in the way of strong, direct writing. Often used by lazy writers. What’s the difference between The cake was very good and The cake was good? Wasted keystrokes.
