Answer 2

If only he could reach a table in the restaurant unsuspected, success would be his.

use unless and rewrite​

Unless he reaches a table in the restaurant unsuspected, he would fail.

Unless is a conjunction that means 'unless if.' The clause after unless is a subordinate clause (sc) that requires the main clause (mc) to complete the sentence. We don't use will or would in the subordinate clause since unless is a conditional word (like if): I'll meet you at two o'clock unless I hear from you.
