<p>Yes, but the probability to use 在 is much hight than without it. The reason is 咖啡馆 is a place and there is a verb phrase following it。actually， it is omitted because the information and word categories in the sentence.</p>

<p>I found this two examples at the same Chinese lesson text, but it is not explained why 在 is omitted in one of them:</p>
<ol>
<li>你们明天在咖啡馆见面</li>
<li>你们明天咖啡馆见面</li>
</ol>
<p>Is 在 optional?</p>

Hopefully we can get answers which cite e.g. grammar textbooks.  "A random person on the Internet says so" is not a reliable answer.
