<u>Answer:</u>
In a restaurant, you are usually kindly attended by a waiter who takes your food order. And, therefore, you must respond kindly.
To order the food you may use the phrase <em>I would like ... for me...</em>, followed by <em>please</em>.
These phrases in Spanish are translated to:
<h2>quisiera... para mí... </h2>
I would like ... for me ...
<h2>por favor
</h2>
please
For example:
Yo <em><u>quisiera</u></em> una carne asada <em><u>para mí</u></em>, <em><u>por favor
</u></em>
I <em><u>would like</u></em> a roast <u><em>for me</em></u>, <u><em>please
</em></u>
The other options:
<em>De nada</em> (you are welcome) and <em>mucho gusto</em> (Glad to meet you) do not match with this context, hence <u>are incorrect.
